The GTX 1080 has GDDR5X, which has ECC. I was able to dial in my memory OC on that card by increasing the clock then running memory throughput benchmarks until the throughput was maxed out. At the point where errors start the theroughput would decrease, but nothing would fail.
Assuming stationary processes this is pretty nice. Maybe bump back 5% for margin.
